'It's not gambling. Look at what a sure thing this bet is!'. Again, wild.

The regulation is often at the state level, the most representative form of legislation possible, often varying from state to state creating the freest system/market where you can chose to live in a less or more regulated state.

When at the federal level it is as the DIRECT result of the social impact it previously caused not because the government just wanted to restrict freedom but freedom was tried and in this situation not sustainable on a societal level.
